Some times the rear back-up camera dash board display will turn off while maneuvering in reverse. sometimes it will turn off to answer the phone, while the car is moving in reverse. and other times it will flicker then return to the home page. the dealer says its working normally and they can't duplicate the problem. however its happened at least a half dozen times since i've owned the car, in the past 2 yrs. the problem seems to happen when the car is moving in reverse usually when backing out of a parking space with parked cars on either side of me. the car has a sony information center and back-up camera and cross traffic alert and speed sensing radar. other then that the car drives impeccably.
